{sup 63}Cu and {sup 115}In NMR study of CuInS{sub 2} semiconductor

Two CuInS{sub 2} semiconductor samples synthesized from chemical elements with the equiatomic cation ratio (N{sub Cu}/N{sub In} = 1) and either an excess or stoichiometric sulfur content have been investigated by {sup 63}Cu and {sup 115}In nuclear magnetic resonance. The spectra were recorded on a B...

Description
Summary:Two CuInS{sub 2} semiconductor samples synthesized from chemical elements with the equiatomic cation ratio (N{sub Cu}/N{sub In} = 1) and either an excess or stoichiometric sulfur content have been investigated by {sup 63}Cu and {sup 115}In nuclear magnetic resonance. The spectra were recorded on a Bruker Avance-400 spectrometer at a temperature of 290 K and frequencies of 106.14 MHz ({sup 63}Cu) and 87.67 MHz ({sup 115}In). Numerical simulation made it possible to determine the quadrupole coupling constants: 0.34 MHz ({sup 63}Cu) and 1.1 MHz ({sup 115}In). For the samples synthesized with excess sulfur (above stoichiometry), distortions are revealed in both the {sup 63}Cu and {sup 115}In spectra.
